Patent EP-0375461-A3 (EP)
Title: Semiconductor device being packaged
IPC: H01L23/64
Filed: 1989-12-22
Abstract: A semiconductor device having an internal wiring layer (123) 
which functions as a transmission path in a package (100), the 
internal wiring layer comprising a fine wiring portion (131) for 
allowing a many-pin structure of the semiconductor device and 
a low electric resistance wiring portion (133) for decreasing the 
internal wiring resistance. For the fine wiring portion and 
the low electric resistance wiring portion, two grounding 
layers for individually forming a micro strip structure are 
disposed. Alternatively, a grounding layer (115) for forming the 
fine wiring portion in a micro strip structure and another 
grounding layer (111) for forming the low electric resistance 
wiring portion in a coplanar structure are disposed. By 
considering the distance between these grounding layer and 
each wiring portion, the characteristic impedance of the 
entire internal wiring layer is controllably kept constant.

Title: Method for producing a pigment mix for coating paper
IPC: D21H19/40
Filed: 1989-10-11
Abstract: The invention concerns a method for preparing a pigment 
mix to be used in the coating of a paper web, in which 
method a water slurry is prepared containing talc and at 
least one other component of the coating mix such as 
calcined clay or calcined talc. The invention is 
characterized by first dispersing talc into a water slurry 
and thereafter mixing the second component of the coating 
mix in dry form into the talc slurry prepared in the first 
stage. This kind of a direct mixing method results in a 
pigment mix allowing preselected opacity and printability 
values of the paper to be attained using an appreciably 
lower proportion of the second component, such as calcined 
clay or calcined talc, in the mix.
Patent EP-0369962-A3 (EP)
Title: Method for processing signals in a channel
IPC: H04L25/08
Filed: 1989-10-31
Abstract: In a signal processing channel, digital values, correspond­
ing to a digitized incoming analog signal representative of coded 
binary data, are processed. Using a state-dependent sequence 
detection algorithm appropriate functional expressions of digital 
sample values are precomputed at each cycle of the digitizing 
clock for a preselected number of bits ahead of the current bit. 
Preselected ones of these expressions are compared against 
corresponding thresholds to provide respective binary decision 
outputs that, with state values corresponding to the current 
state, determine state values for the next state and decode one 
bit of coded binary data at each clock cycle. Programmed values 
generated for the thresholds may be adaptively modified according 
to changes in sample values in the incoming analog signal rela­
tive to corresponding expected sample values. Different thres­
holds are used for positive and negative phases of the analog 
signal shape to accommodate signal shape asymmetry. Because the 
decoder is programmable, threshold constants at different tracks 
or bands of tracks in a disk file can be changed to optimize 
performance at all tracks of the file.

Title: Gear change device for selectively switching on one of two ratios of a distribution- or intermediate-gearing
IPC: F16H61/70
Filed: 1989-07-05
Abstract: A gear change device for selectively switching on one of two ratios (4, 6 or 5, 7) of a distribution - or intermediate gearing (15), in particular for selectively switching on the cross-country gear in heavy-duty trucks, has a gear change element (9 to 12) which is designed as a socket (9) having a synchronising mechanism (10, 11), which socket (9) is adjustable via an actuating device (22, 23) during driving when clutch (2) is disengaged. To prevent overspeeding of the engine, a locking mechanism (26) is provided which, controlled by a speed monitor (27), only permits switching back into the cross-country gear (5, 7) if the engine speed is in a predeterminable lower range when the clutch (2) is disengaged. <IMAGE>
Patent EP-0386462-A3 (EP)
IPC: G06F11/10
Filed: 1990-02-02
Abstract: In a memory system comprising a plurality of memory 
units (10) each of which possesses unit-level error 
correction capabilities (20) and each of which are 
tied to a system level error correction function (30), 
memory reliability is enhanced by providing means for 
fixing the output of one of the memory units at a 
fixed value in response to the occurrence of an 
uncorrectable error in one of the memory units. This 
counter-intuitive approach to the generation of forced 
hard errors nonetheless enhances overall memory system 
reliability since it enables the employment of the 
complement/recomplement algorithm which depends upon 
the presence of reproducible errors for proper 
operation. Thus, chip level error correction systems, 
which are increasingly desirable at high packaging 
densities, are employed in a way which does not 
interfere with system level error correction methods.

Title: Subscriber equipment for transmitting temporarily stored data to a paging receiver fitted with an acoustical and/or optical output device
IPC: H04M1/658
Filed: 1990-06-25
Abstract: 2.1. Subscriber devices in the form of answering machines with information recording, call forwarding and remote interrogation are known. If the owner of the answering machine is travelling, the call signal, after the message of the caller has been recorded, can be automatically forwarded to a paging receiver via the European paging service. The answering machine contains an automatic dialler for forwarding the call. Furthermore, a paging service (City-Ruf) is known in which not only paging signals but also digits and short text (Display-Paging) are transmitted and displayed on the display device of the paging receiver. 2.2. Using a network gateway from the line-connected telecommunications network to a radio paging service, the novel subscriber device provides for fast information transmission of messages temporarily stored in the subscriber device. For this purpose, the subscriber device contains, in addition to the additional buffer store, a microprocessor which, using stored dialling information items, sets up a connection to a paging receiver and then reads out the temporarily stored message. 2.3. The novel subscriber device can be used in all communication networks for switched connections and ensures that a called subscriber who is travelling can respond quickly to a call. <IMAGE>
Patent EP-0407855-A3 (EP)
Title: Planetary stranding machine
IPC: D07B3/06
Filed: 1990-07-03
Abstract: In planetary stranding machines, in which the rotor consists essentially of a supporting tube, to which disc-shaped supporting plates for the rotatably mounted bobbin carriers are connected, for purely constructional reasons the rotor cannot be designed with the necessary bending resistance, thus resulting here in limitations to the maximum permissible rotational speed which lead to a limitation of the production capacity. 
<??>The arrangement on the supporting tube (6) of longitudinal webs (7) directed radially outwards and distributed uniformly on the circumference affords a greater resistance which permits higher rotational speeds. Furthermore, if the supporting plates (12) on the one hand and the axes of rotation (13) of the bobbin carriers (9) on the other hand are arranged at an angle to the supporting tube (6), this produces a considerable reduction of the flight-circle diameter which in turn allows an increased operating speed, so that the production capacity can be increased.

Title: Half duplex RF transceiver having low transmit path signal loss
Inventor: GREEN DONALD RICHARD
IPC: H04B7/08
Filed: 1995-07-27
Abstract: A circulator section (100) in a transceiver (20)
receives a transmit signal and an antenna signal and provides
them respectively to an antenna (10) and to an electronic
switch (150). The electronic switch (150) operates
synchronously with the duplex mode of the transceiver (20) to
connect the antenna (10) to a receiver (1) when the transceiver
(20) is in receive mode, and to a matched load (38) when it is
in transmit mode. Since the signal path of any portion of the
transmit signal reflected by a mismatched antenna is terminated
by the load (38), power which otherwise might be reflected back
to the transmitter (2) and thereby damage it is instead
absorbed by the matching load (38).
